Abstract:

In the summer of 2020, a fragment of a cow's rib with a Cyrillic inscription was found at excavations in Novgorod. The place of the find is one of the richest boyar estates in the Lyudin quarter of medieval Novgorod. The time of the document hitting the ground is the last quarter of the 13th—the first twenty years of the 14th century. The inscription is fully preserved, it contains a whole readable message. The historical and cultural value of the find lies in the content of its compact inscription: it is unique evidence of a bride-price agreement. The terminology is of value: the bride, on whose behalf the text is written, and the groom (addressee) are designated not by their own names (Christian or pre-Christian), but by the images of the ritual folklore of the wedding — kuna ‘marten’ (she) and sobol’a ‘sable’ (he). The bride-price is no less interesting. The text communicates an idea of a dialogue between the two sides of the marriage ritual. The new evidence of the matrimonial rites and the associated oral-written communication expands our understanding of this sphere of medieval culture and allows us to correct some interpretations of the few birch bark letters on the topic of marriage.

Abstract:

This study has the aim of knowing the views of the people of Bone Regency about panaik money and the impact of panaik money on the community in Tanete Riattang District, Bone Regency. This type of research is field research using qualitative descriptive analysis through social and Islamic legal approaches.The results of the study indicate that panaik money is a custom of the Bugis community in Tanete Riattang District, Bone Regency, which describes a person's degree or prestige in his community. The impact of panaik money for the community in Tanete Riattang District, Bone Regency, has a positive impact and a negative impact. Positive impacts, namely; so that the men try and earnestly in earning a living or living expenses, lighten the burden on the women in organizing the wedding party and the establishment of friendship between the families of the prospective bride and groom. The negative impact itself is the occurrence of crossbreeding events, making it difficult to implement Islamic law on marriage, extravagance or rah-rah, and getting pregnant before marriage.This research implies that the government and local communities pay attention to the impact of panaik money culture, so that it does not have a broad negative impact, so it is necessary to educate the community so that they carry out customs according to the ability of the community and have a positive impact on human survival in the institution of marriage.

Abstract:

Temper is an essential element in pottery making in many parts of the world and in large parts of prehistory. Furthermore, it readily lends itself to qualitative and quantitative study without advanced equipment. Since all non-plastic materials in theory may be used as temper, variations in the choice of type and quality (amount, grain size) are important indications of craft traditions, functional differences and contacts between different areas. Even other, more elusive considerations might lie behind the choice of temper. Like the bride who should wear something new, something old, something borrowed and something blue, the tempering of pottery may include materials which allude to other objects or situations, thus establishing a coherence between the pot and other phenomena. Some new examples of special tempering with bone and chaff in pottery from the Iron Age in Scandinavia are presented for discussion.

Abstract:

Using the Excel programme a database was created of 332 horses born at the horse breeding station (ŠCHK) – Měník after 1 August 1993. The database was transferred to the Unistat 6.5 programme and by means of the linear model GLM evaluated were some effects on horse performance in the horse breeding station (ŠCHK) – Měník. For the evaluation of breeding activities we selected a few important effects on the herd, i.e. sex, father (line), mother (family) and year of birth. For each horse of the database we identified the basic measurements, results from the score on entry into the studbook and performance tests. The database included a total of 15 homogeneous families and their numerous offspring. The following stallions influenced the herd: 366 Taarlo, 616 Erudit, 2626 Sahib Kubišta, 525 Tarlo Kubišta, 1004 First Bride, 2805 Le Patron, 630 Przedswit Makebo, 1028 Manillon Rouge and 2640 Radegast. Rating based on the variable score on entry into the studbook and the basic performance test was statistically the highest in 1994. In dependence on the basic performance test the rating of stallion 1028 Manillon Rouge was the highest with an average of 7.8 scores. The families Forma and Gama S reached the statistically significantly highest scores for the dependent variables of the testing rearing house and heart girth. The mares have a statistically significantly larger heart girth than the stallions. Stallion 2640 Radegast had a bone diameter of 22 cm which was statistically significantly the highest rating; stallion 616 Erudit had the lowest rating.

Abstract:

AbstractIntroduction:Craniofacial fibrous dysplasia commonly affects the larger mandible and the maxillary bones. Although involvement of the frontal, temporal and sphenoid bones has been described, fibrous dysplasia of the nasal bone has not been previously described; the two cases reported here have been made rarer by their isolated involvement. Clinical management is dependent on disease activity and patient symptoms.Objective:To present two cases of isolated fibrous dysplasia of the nasal bone: a 46-year-old woman with gradual widening of the nasal bridge and a 47-year-old man with an incidental finding of a nasal bone mass.Method:Two case reports.Results:The 46-year-old woman underwent excision of the lesion while the 47-year-old man opted for watchful waiting.Conclusion:We have presented the first case reports of fibrous dysplasia of the nasal bone. The care of these patients should be customised to their needs and wishes.

Abstract:

Background:This literature review was undertaken to determine if commonly held views about the benefits of a bone bridge technique are supported by the literature.Methods:Four databases were searched for articles pertaining to surgical strategies specific to a bone bridge technique of the transtibial amputee. A total of 35 articles were identified as potential articles. Authors included methodology that was applied to separate topics. Following identification, articles were excluded if they were determined to be low quality evidence or not pertinent.Results:Nine articles were identified to be pertinent to one of the topics: Perioperative Care, Acute Care, Subjective Analysis and Function. Two articles sorted into multiple topics. Two articles were sorted into the Perioperative Care topic, 4 articles sorted into the Acute Care topic, 2 articles into the Subjective Analysis topic and 5 articles into the Function topic.Discussion:There are no high quality (level one or two) clinical trials reporting comparisons of the bone bridge technique to traditional methods. There is limited evidence supporting the clinical outcomes of the bone bridge technique. There is no agreement supporting or discouraging the perioperative and acute care aspects of the bone bridge technique. There is no evidence defining an interventional comparison of the bone bridge technique.Conclusion:Current level III evidence supports a bone bridge technique as an equivalent option to the non-bone bridge transtibial amputation technique. Formal level I and II clinical trials will need to be considered in the future to guide clinical practice.Clinical relevanceClinical Practice Guidelines are evidence based. This systematic literature review identifies the highest quality evidence to date which reports a consensus of outcomes agreeing bone bridge is as safe and effective as alternatives. The clinical relevance is understanding bone bridge could additionally provide a mechanistic advantage for the transtibial amputee.

Abstract:

Objective: To examine the effect of migration of the germ of the lateral incisor into the bone for eruption factors on bone bridge resorption. Methods: Twenty-five subjects who underwent secondary alveolar bone graft were enrolled. The volume of the alveolar bone grafts immediately after the operation (V1), bone bridge formation 6 months postoperatively (V2), and tooth (teeth) migration into the bone bridge (Vt) were measured using a computed tomography (CT) image analyzer. Based upon these measurements, the following points were examined: (1) the correlation between the tooth-occupied ratio (Rt = Vt/V2 × 100) and the ratio of bone bridge resorption (Rv = (V1 − V2)/ V1 × 100); and (2) comparison of the tooth-occupied ratio (Rt) and the ratio of bone bridge resorption (Rv) between the groups with and without the germ of the lateral incisor. Results: A significant negative correlation was found between Rv and Rt (p < .001). Comparison of Rv and Rt between the groups with and without a germ of the lateral incisor revealed that both indices were significantly higher in the former group than the latter one (p < .05). Conclusion: In cleft lip and palate patients with a germ of the lateral incisor, it is beneficial to carry out secondary bone grafting to the alveolar cleft at the age of 5 to 7 years, preceding eruption of the canine, in order to form a good bone bridge that will facilitate eruption of the lateral incisor and subsequent normal dentition and occlusion.

Abstract:

Objectives The aim of this study was to demonstrate the clinical applicability of limited cone beam computed tomography (Dental 3D-CT) for assessment of bone-grafted alveolar cleft. Patients and Methods Seventeen bone bridges were examined after alveolar bone grafting in 13 patients with cleft lip and palate. All bone bridges, including cleft-adjacent teeth, were examined by plain radiography and the Dental 3D-CT imaging system. Results The plain radiographs showed the approximate condition of the bone bridge and cleft-adjacent teeth. The Dental 3D-CT images clearly showed precise three-dimensional (3D) morphology of the bone bridge, 3D relationships between the bone bridge and the roots of cleft-adjacent teeth, and their periodontal condition. In addition, the conditions surrounding dental implants installed in the bone bridge could be observed three-dimensionally. Conclusions The results indicate that the Dental 3D-CT imaging system is suitable for clinical assessment of alveolar bone grafting before and after installation of dental implants or orthodontic treatment of the cleft-adjacent teeth.

Abstract:

Marriage is a spiritual bond between a man and a woman to form a happy and eternal home or family based on the Godhead. Nevertheless, many divorces still occur in the community today. Suscatin is a solution provided by the Government to overcome divorce which is getting higher every year. But there are still obstacles in the organization of Suscatin. The Suscatin implementation is still done manually, where to conduct the exam the bride and groom write on a piece of paper. In addition, the implementation was carried out on the effective day, so the bride and groom could not attend. For this reason, this research was conducted to design a web-based learning system that can facilitate the Office of Religious Affairs and prospective brides. So that the material about marriage can be studied without any obstacles both in terms of time and place of implementation. It is expected to be able to anticipate disputes and divorce as well as violence in the family in order to create a sakinah, mawaddah, and rahmah family

Abstract:

Objective.Diffuse idiopathic skeletal hyperostosis (DISH) is characterized by flowing bony bridges on the right side of the spine. Knowledge of the development of these spinal bridges is limited. The current longitudinal computed tomography (CT) study was designed to bridge this gap.Methods.Chest CT scans from elderly males with 2 scans (interval ≥ 2.5 yrs) were retrospectively included. Using the Resnick criteria, a pre-DISH group and a definite DISH group were identified. A scoring system based on the completeness of a bone bridge (score 0–3), extent of fluency, and location of the new bone was created to evaluate the progression of bone formation.Results.In total, 145 of 1367 subjects were allocated to the DISH groups with a mean followup period of 5 years. Overall prevalence of a complete bone bridge increased in the pre-DISH group (11.3% to 31.0%) and in the definite DISH group (45.0% to 55.8%). The mean bridge score increased significantly in both the pre-DISH and definite DISH group (p < 0.001). The new bone gradually became more flowing and expanded circumferentially.Conclusion.Over the mean course of 5 years, the new bone developed from incomplete, pointy bone bridges to more flowing complete bridges. This suggests an ongoing and measurable bone-forming process that continues to progress, also in established cases of DISH.

Abstract:

Isotretinoin, a vitamin A derivative, is known to induce premature epiphyseal closure. We report the case of a 9-year-old boy with neuroblastoma who demonstrated premature epiphyseal closure after 1 year of isotretinoin treatment (72.3 mg/m2/day). A bone bridge developed on the bilateral proximal tibial growth plate resulting in genu varum. We performed hemiepiphysiodesis on the bilateral proximal tibia in anticipation of the spontaneous resolution of the bone bridge. Genu varum on the left side was corrected with the resolution of bone bridge. For the remaining bone bridge on the right side, arthroscopy-assisted physeal bar resection was performed, and genu varum on the right lower extremity was also corrected. A regular review of the alignment of the upper and lower limbs is necessary to provide timely intervention in patients using isotretinoin, considering the possibility of premature epiphyseal closure.

Abstract:

ABSTRACTTannerella forsythiais strongly associated with chronic periodontitis, an inflammatory disease of the tooth-supporting tissues, leading to tooth loss.Fusobacterium nucleatum, an opportunistic pathogen, is thought to promote dental plaque formation by serving as a bridge bacterium between early- and late-colonizing species of the oral cavity. Previous studies have shown thatF. nucleatumspecies synergize withT. forsythiaduring biofilm formation and pathogenesis. In the present study, we showed that coinfection ofF. nucleatumandT. forsythiais more potent than infection with either species alone in inducing NF-κB activity and proinflammatory cytokine secretion in monocytic cells and primary murine macrophages. Moreover, in a murine model of periodontitis, mixed infection with the two species induces synergistic alveolar bone loss, characterized by bone loss which is greater than the additive alveolar bone losses induced by each species alone. Further, in comparison to the single-species infection, mixed infection caused significantly increased inflammatory cell infiltration in the gingivae and osteoclastic activity in the jaw bones. These data show thatF. nucleatumsubspecies andT. forsythiasynergistically stimulate the host immune response and induce alveolar bone loss in a murine experimental periodontitis model.

Abstract:

Introduction and objective Ankylosing spondylitis (AS) has characteristics of spinal bone bridge and fusion. Although BMD reduction in AS may be presumed to be due to spinal inflammation, this study was designed to confirm whether immobilization of the spine due to syndesmophytes is related to BMD reduction, as immobilization itself is a risk factor for BMD reduction. Methods Among male patients diagnosed with AS according to the modified New York criteria, those who underwent bone density tests with quantitative computed tomography (QCT) were retrospectively analyzed through a chart review. The correlation between the presence or absence of bone bridges for each vertebral body level of the L spine confirmed with radiography and BMD confirmed with QCT was analyzed. Results A total of 47 male patients with AS were enrolled. The mean patient age was 46.8 ± 8.2 years, and the mean disease duration was 7.9 ± 6.4 years. The trabecular BMD of the lumbar spine (L1-L4) ranged from 23.1 to 158.45 mg/cm3 (mean 102.2 ± 37 mg/cm3), as measured with QCT. The lumbar BMD measurements showed that 30 patients (63.8%) had osteopenia or osteoporosis. Bone bridge formation showed a negative correlation with BMD. Low BMD was significantly correlated with bone bridge in the vertebral body (p < 0.05). Positive correlations were observed between bone bridge score and BASMI flexion score, whereas significant negative correlations were found between BMD and BASMI flexion score (p < 0.05). Conclusion Decreased mobility of the vertebrae due to bone bridge formation affects the decrease in BMD in patients with AS.

Abstract:

The number of supporting dental implants is an important criterion for the surgical outcome of dental bridge fixation, which has considerable impact on biomechanical load transfer characteristics. Excessive stress at the bone–implant interface by masticatory loading may result in implant failure. The aim of this study was to evaluate the impact of the number of implants supporting the dental bridge on stress in neighboring tissues around the implants. Results of the study will provide useful information on appropriate surgical techniques for dental bridge fixation. In this study, osseointegrated smooth cylindrical dental implants of same diameter and length were numerically analyzed, using three-dimensional bone–implant models. The effect of the number of supporting implants on biomechanical stability of dental bridge was examined, using two, three and four supporting implants. All materials were assumed to be linearly elastic and isotropic. Masticatory load was applied in coron-apical direction on the external part of dental bridge. Finite Element (FE) analyses were run to solve for von Mises stress. Maximum von Mises stresses were located in the cervical line of cortical bone around dental implants. Peak von Mises stress values decreased with an increase in the number of implants that support the dental bridge. Results of this study demonstrate the importance of using the correct number of supporting implants to for dental bridge fixation.

Abstract:

Cleft lip and palate is a congenital disorder including cleft lip, and/or cleft palate, and/or alveolar cleft, with high incidence.The alveolar cleft causes morphological and functional abnormalities. To obtain bone bridge formation and continuous structure between alveolar clefts, surgical interventions are performed from infancy to childhood. However, desirable bone bridge formation is not obtained in many cases. Regenerative medicine using mesenchymal stem cells (MSCs) is expected to be a useful strategy to obtain sufficient bone bridge formation between alveolar clefts. In this study, we examined the effect of human umbilical cord-derived MSCs by transplantation into a rat experimental alveolar cleft model. Human umbilical cords were digested enzymatically and the isolated cells were collected (UC-EZ cells). Next, CD146-positive cells were enriched from UC-EZ cells by magnetic-activated cell sorting (UC-MACS cells). UC-EZ and UC-MACS cells showed MSC gene/protein expression, in vitro. Both cells had multipotency and could differentiate to osteogenic, chondrogenic, and adipogenic lineages under the differentiation-inducing media. However, UC-EZ cells lacked Sox2 expression and showed the lower ratio of MSCs than UC-MACS cells. Thus, UC-MACS cells were transplanted with hydroxyapatite and collagen (HA + Col) into alveolar cleft model to evaluate bone formation in vivo. The results of micro computed tomography and histological staining showed that UC-MACS cells with HA + Col induced more abundant bone formation between the experimental alveolar clefts than HA + Col implantation only. Cells immunopositive for osteopontin were accumulated along the bone surface and some of them were embedded in the bone. Cells immunopositive for human-specific mitochondria were aligned along the newly formed bone surface and in the new bone, suggesting that UC-MACS cells contributed to the bone bridge formation between alveolar clefts. These findings indicate that human umbilical cords are reliable bioresource and UC-MACS cells are useful for the alveolar cleft regeneration.

Abstract:

Pendahuluan: Radiografi periapikal dapat digunakan untuk mendeteksi tulang alveolar pada perawatan gigi tiruan jembatan. Pembuatan gigi tiruan jembatan harus memenuhi syarat-syarat biologis. Apabila adaptasi marginal buruk, penempatan margin intracrevicular terlalu dalam, permukaan restorasi yang kasar dan restorasi yang overkontur dapat menyebabkan peradangan lokal seperti inflamasi gingiva, peningkatan kedalaman probing dan kehilangan tulang alveolar. Tujuan penelitian ini untuk mengetahui bagaimana deskripsi tulang alveolar pasca perawatan jembatan di RSGM UNPAD ditinjau dari radiografi periapikal. Metode: Jenis penelitian deskriptif dengan populasi adalah seluruh hasil radiograf periapikal pada pasien sebelum dan sesudah perawatan jembatan posterior yang datang ke RSGM Unpad dan sampel adalah radiograf sebelum dan sesudah perawatan jembatan posterior sebanyak 17 pasien setelah insersi 1 minggu dan 2 pasien setelah insersi 4 minggu. Pengukuran ketinggian tulang alveolar menggunakan Metode Proksimal RABL (Radiographic Alveolar Bone Loss) yang dihitung memakai jangka sorong. Hasil : Kehilangan tulang alveolar setelah insersi 1 minggu pada mesial dan distal yaitu 0,003 mm, setelah insersi 2 minggu 0,007 mm pada mesial dan 0,025 pada distal,setelah insersi 3 minggu 0,025 mm pada mesial dan 0,019 mm pada distal, setelah insersi 4 minggu 0,075 mm mesial dan 0,063 mm distal. Simpulan: Pasca perawatan jembatan, ditinjau dari radiografi periapikal, terdapat kehilangan tulang alveolar ringan berdasarkan metode proksimal RABL.Kata kunci : Gigi tiruan jembatan, radiograf periapikal, tulang alveolar. ABSTRACTIntroduction: Periapical radiography can be used to detect alveolar bone in bridge denture treatment. The making of bridge denture must fulfil biological requirements. Poor marginal adaptation will lead to deeper intracrevicular margin placement, rough surfaces, over contour restoration can cause local inflammation such as gingival inflammation, increased probing depth and alveolar bone loss. The purpose of this research was to know the description of alveolar bone after bridge denture treatment reviewed through periapical radiography. Methods: This research was descriptive with the population of all radiograph periapical treatment of posterior bridge in Universitas Padjadjaran Dental Hospital and the sample was radiograph periapical before and after bridge treatment of as much as 17 patients after 1-week insertion and 2 patients after 4-weeks insertion. Alveolar bone height measurements was carried out using the RABL (Radiographic Alveolar Bone Loss) proximal method calculated using the Vernier callipers. Results: The results indicated that alveolar bone loss occurred after 1-week insertion on the mesial and distal was 0.003 mm; after 2-weeks insertion was 0.007 mm on the mesial and 0.025 mm on the distal; after 3-weeks insertion was 0.025 mm on the mesial and 0.019 mm on the distal; and after 4-weeks insertion was 0.075 mm on the mesial and 0.063 mm on the distal. Conclusion: Post bridge treatment, in terms of periapical radiography, found a mild alveolar bone loss based on the proximal RABL method. Keywords: Bridge denture, periapical radiograph, alveolar bone.

Abstract:

The bonding between pavement and a steel bridge deck is a key component affecting the structural integrity of steel deck pavement and delamination is a major cause. The bonding interface of steel deck pavement was systematically investigated to evaluate the interactive influences of factors, such as the air void of the asphalt concrete pavement, the surface roughness of the steel deck, the thickness of the zinc-rich epoxy primer, and the waterproof bonding membrane, on the bond strength of the pavement interface, through simulated loading, brine immersion, pull-off, and interface observation experiments. The results show that a low air void (<3.0%) was a necessary condition for the corrosion resistance and bonding reliability of the steel deck pavement structure, and a zinc-rich epoxy primer provided an additional guarantee for corrosion resistance of the steel deck pavement; additionally, the combination of steel deck plate roughness in the range of 120–140 μm and zinc-rich epoxy primer thickness in the range of 80–110 μm led to a high bond strength, which was also conducive to the corrosion resistance of the steel bridge plate. The steel deck pavement structure should be designed through combinatorial optimization of multiple factors to create an integrated waterproof and anticorrosion bonding system.

Abstract:

Indonesia is a maritime country with the potential fisheries resources. However, utilization only revolves around the meat, while other parts have not been used optimally, especially fish bones which have the potential to produce collagen, so it needs to be developed. The aims of this study ware extracted collagen from bone of Lutjanus sp. and determine its the Anticancer activity. The collagen was extracted by using hydroextraction method and identification by FTIR. The initial screening anticancer activity was done by using Brine Shrimp Lethality Test (BSLT) method for toxicity assay. The results showed that the yield of collagen was 4.535% with protein concentration was 8,815 mg/mL. Identified collagen from spectrum of amide A, B, I, II, and III at 3421.72; 2926.01; 1651.07; 1541.12; 1240.23 cm-1. The toxicity test was shown in LC50 values of 8,760 μg/mL. The collagen from Lutjanus sp. bone can be used as natural anticancer agent.

Abstract:

Purpose The article compares physeal recovery after insertion of autologous cartilage and a conventional fat graft in a standardized porcine physeal gap model. Presence of a bone bridge was the primary outcome. Methods Ten porcines in two groups of five were included in a paired design. A standardized physeal gap in the distal femur was made in all animals. One group (n = 5) was randomized for deposition of autologous cartilage and a Tisseel® or Tisseel® alone. The autologous cartilage was harvested from the femoral articular surface. The other group was randomized for fat grafting or no grafts at all. All animals were housed for 14 weeks. Magnetic resonance imaging (MRI) was performed at 14 weeks prior to euthanasia. The physis was harvested for histology. Results MRI – Three bone bridges were seen in the fat grafted gaps. All empty gaps formed a bone bridge. No gaps filled with autologous cartilage and Tisseel® resulted in bone bridges. One gap filled with Tisseel® only caused a bone bridge. Histology – The cartilage grafted gaps recovered with physeal-like cartilaginous tissue in histological analysis. Conclusions Fat grafts seems ineffective in preventing bone bridges. The use of autologous cartilage may be superior to the current treatment. However, donor site complications were not investigated. The study serves as a proof of concept study and requires further investigation. Level of evidence III

Abstract:

The bridge is an important infrastructure in the transportation system, namely as a means of crossing the river, as well as connecting between cliffs. The bridge has various shapes, one of which is a curved bridge with cables. Arch bridge is suitable for trident bridge because it has a long span. Through this thesis, the author tries to plan an alternative building over an existing bridge with a curve type. Preliminary planning data includes the total length of the existing bridge 150 m wide by 9 m. The planning method used is LRFD (Load Resistance Factor Design) and uses the Staad Pro v8i assist program. In this planning the author planned floor plates, elongated girders, transverse girders, parent girders, wind bonds, cables, joints and elastomers. From the results of the analysis obtained the structure of the building over the bridge for floor plates using the principal bones D10-200 and reinforcements for D13-200, the elongated steel gelagar profile WF 500 x 200 x 10 x 16, the steel transverse gelagar profile WF 800 x 350 x 16 x 36, the parent steel gelagar profile WF 700 x 300 x 13 x 24, steel steel bond double profile L250 x 250 x 35, for the dimensions of dyform cable D38, for laying using elastomer size 120 cm long, width 120 cm, height 26 cm

Abstract:

Background: High-energy trauma is an important cause of compound fractures of long bones that in turn results into bone gap due to bone loss or high communition with resultant displacement of minute fracture fragments and hence non-union. Bone resorption or surgical excision for infection or tumour also leads to gap non-unions.Methods: Forty-one patients having fracture of long bones of extremities with a bone gap of upto 2 inches were enrolled and were treated with autogenous bone grafting and calcium hydroxyapatite (CHA) blocks along with fixation by a locked compression plate (LCP) and plaster slab. The average follow-up period was ten months. One patient was excluded from the study due to drop out from follow up.Results: In 23 (57.5%) patient’s radiological union occurred by 24-26 weeks. In 16 (40%) patients, radiological union was seen between 26-28 weeks, while in one (2.5%) patient union was seen at 30 weeks. Also, it was seen that smaller the length of gap, the faster was the union. Excellent results were seen in the majority of 25 patients (62.5%), good results in 11 patients (27.5%), fair results in 3 patients (7.5%) and poor outcome in 1 patient (2.5%). Also, it was seen that smaller the gap size, better was the outcome.Conclusions: The technique of bridge plating using internal fixator i.e. LCP along with autogenous corticocancellous bone graft and CHA blocks is a fairly good technique to treat gap non unions. It has its own advantages of avoiding complications associated with large external frame constructs. However, larger gap size limits the usefulness of this technique.

Abstract:

A combined tympanoplasty method, the mobile-bridge tympanoplasty, has been applied at the Clinic for Ear, Nose and Throat Diseases in Novi Sad since 1998. Mobile-bridge tympanoplasty is performed at our Clinic by applying Feldmann?s procedure utilizing a microsurgical oscillating saw. It is a combination of closed and open techniques for surgical treatment of middle ear diseases. In addition to this technique, a method for reconstruction of the posterior bone wall of the external auditory canal was introduced. This procedure is applied in cases of damage or impairment of the bony ear canal wall using mastoid cortical temporal bone graft or modeled cartilage of the concha. Maintenance of general anatomical relations in the middle ear enables good ventilation of pneumatic spaces of the middle ear and Eustachian tube permeability, thus providing good conditions for ossicular chain reconstruction. The incidence of recurrent cholesteatoma in combined mobile-bridge tympanoplasty and tympanoplasty with reconstruction of the posterior bone wall was 6% in total. The incidence values for the recurrent cholesteatoma in closed tympanoplasty and in cases of open techniques were 10%. Mobile-bridge tympanoplasty and reconstruction of the posterior bone wall of external auditory canal are methods of choice in surgical treatment of middle ear cholesteatoma that progressed to the attic space, sinus tympani and facial recess.

Abstract:

We sought to describe the bone bridge technique in adults, and present a variation for use in children, as well as to present its applicability as an option in elective transtibial amputations. This paper presents a prospective study of 15 transtibial amputations performed between 1992 and 1995 in which the bone bridge technique was employed. The patients' ages ranged from 8 to 48 years, with an average of 22.5 years. This technique consisted of the preparation of a cylinder of periosteum extracted from the tibia and with cortical bone fragments attached to it to promote a tibiofibular synostosis on the distal extremity of the amputation stump. We noted that the cortical bone fragments were dispensable when the technique was employed in children, due to the increased osteogenic capacity of the periosteum. This led to a variation of the original technique, a bone bridge without the use of the cortical bone fragments. RESULTS: The average time spent with this procedure, without any significant variation between adults and children, was 171 minutes. The adaptation to the definitive prosthesis was accomplished between 20 and 576 days, with an average of 180 days. Revision of the procedure was necessary in 3 amputations. CONCLUSIONS: This technique may be employed in transtibial amputations in which the final length of the stump lies next to the musculotendinous transition of the gastrocnemius muscle, as well as in the revision of amputation stumps in children, where the procedure has been shown to be effective in the prevention of lesions due to excessive bone growth.

Abstract:

Object The object of this study was to propose an alternative procedure to the classic decompressive hemicraniectomy using an “in-window” craniotomy and a “bridgelike” duraplasty. Methods The authors performed a large, almost rectangular craniotomy involving the frontal, temporal, and parietal bones and part of the occipital squama in 5 patients. The dura mater is opened and its area is enlarged using a rectangular dural patch of the surgeon's choice in the form of a bridge between the anterior and posterior dural edges. With a vertical cut, the bone flap is divided into 2 similarly sized pieces that function as “window lids.” The outer frontal and occipital sides of the bone are tied to the skull border at 2 points to function as a hinge joint. The angle of the bone cut must be beveled outward (inclination ~ 45° of the bone drill or saw) to allow the bone flap to rest on the adjacent skull and prevent its slippage toward the intracranial cavity. Results The above procedures were performed with effective control of intracranial hypertension due to cerebral venous sinus thrombosis, brain trauma, intracerebral hematoma, or malignant cerebral ischemia. Conclusions Decompressive surgery, which uses an in-window craniotomy that gradually opens according to the intracranial pressure, is an alternative solution for deploying autologous material. The procedure has the advantage of obviating the need for a second surgical procedure to close the bone defect, and thus preventing the metabolic cerebral impairment associated with the absence of an overlying skull.

Abstract:

Bacterial infection in orthopedic surgery is challenging because cell wall components released after bactericidal treatment can alter osteoblast and osteoclast activity and impair fracture stability. However, the precise effects and mechanisms whereby cell wall components impair bone healing are unclear. In this study, we characterized the effects of lipopolysaccharide (LPS) on bone healing and osteoclast and osteoblast activity in vitro and in vivo and evaluated the effects of ibudilast, an antagonist of toll-like receptor 4 (TLR4), on LPS-induced changes. In particular, micro-computed tomography was used to reconstruct femoral morphology and analyze callus bone content in a femoral defect mouse model. In the sham-treated group, significant bone bridge and cancellous bone formation were observed after surgery, however, LPS treatment delayed bone bridge and cancellous bone formation. LPS inhibited osteogenic factor-induced MC3T3-E1 cell differentiation, alkaline phosphatase (ALP) levels, calcium deposition, and osteopontin secretion and increased the activity of osteoclast-associated molecules, including cathepsin K and tartrate-resistant acid phosphatase in vitro. Finally, ibudilast blocked the LPS-induced inhibition of osteoblast activation and activation of osteoclast in vitro and attenuated LPS-induced delayed callus bone formation in vivo. Our results provide a basis for the development of a novel strategy for the treatment of bone infection.

Abstract:

The aim of this finite element study was to analyze effect of supporting implants inclination on stress distribution in the bone for a four-unit fixed partial denture. A three-dimensional finite element model of mandibular molar section of the bone to receive implants was constructed. Three implant-supported fixed partial dentures, with null, moderate and wide tilting, of 0°, 15° and 30° implant inclinations, respectively, were modeled. A mechanical load of 10 MPa was applied in coronal–apical direction on bridge framework at the regions of crowns positions. The finite element analysis was performed, and von Mises stress levels were calculated. Peak stress concentration in the cortical bone was observed mostly around the implant necks, in inter-implants line. There was favorable stress distribution during loading, with peak stress being 90.04 MPa for 0°, which decreased to 54.33 MPa for 15° and 46.36 MPa for 30° inclination. The supporting implants inclination in fixed partial denture plays an important role in stress distribution and may be helpful in preventing bone loss and implant failure. This phenomenon is likely to be more pronounced in bones of poor quality. Within the limitation of this study, it seems that the inclination of implants in fixed partial denture has a favorable effect on stress distribution pattern values around the supporting implants.

Abstract:

Background: With the development of transportation in modern China, the incidence of traumatic fracture and the global degree of fracture complexity are increasing. This study explored the use and curative effect of a novel custom-manufactured bridge combined fixation system for traumatic fractures of the femur. The bridge combined fixation system can be tailored to the specific patient's requirements by bending the rods and sliding the attachment modules. Methods: From May 2013 to August 2017, 14 patients with traumatic femur fractures were managed with the bridge combined fixation system. The operation was conducted according to the routine incision approach of femur fracture. The patients were given early postoperative functional rehabilitation exercise. The curative effect was evaluated according to clinical manifestations, postoperative imaging, and a self-developed standard for bone healing. Results: All patients were followed for 12–24 (median: 12.5) months. Fracture healing was assessed based on clinical symptoms and postoperative X-ray. After 3 months, complete weight-bearing on the affected leg was painless. X-ray showed that the fracture line had disappeared by 6–9 months postoperatively and showed bone healing. According to the self-developed standard for bone healing, 13/14 (92.8%) patients achieved excellent/good clinical outcomes. Bone union was achieved in all patients within 2 years. Conclusion: The custommanufactured bridge combined fixation system is simple and can effectively achieve tailored reduction of the fracture. The fixation was stable, with few complications after surgery and with good treatment effect for traumatic fractures.

Two cases of fracture of the radius treated by pinning resulted in severe wrist joint deformity due to premature closure of the epiphysial growth plate. Inappropriate pinning through the physis damaged the growth plate in both cases. They were treated by bone bridge resection with free fat interposition. The bone bar resection was effective in correcting the wrist joint deformity, and bone growth was expected without bone grafting.

Abstract:

Background: The tibial fixation site is considered the weak link in anterior cruciate ligament (ACL) reconstruction, and conflicting results regarding the biomechanical properties of various fixation methods have been reported. Purpose: To examine knots tied over a bone bridge and its biomechanical properties as a suitable tibial fixation method in ACL reconstruction. Study Design: Controlled laboratory study. Methods: We divided 40 fresh-frozen porcine tibiae into 4 equal groups to evaluate flexor tendon grafts set with standard tibial fixation techniques: (1) bone bridge (BB group), (2) suspension button (SB group), (3) combined interference screw and bone bridge (IFS/BB group), and (4) combined interference screw and suspension button (IFS/SB group). Each construct was subjected to cyclic loading (1500 cycles, 50-250 N, 1 Hz) with a servohydraulic materials testing machine to measure elongation; load-to-failure testing (displacement rate: 25 mm/s) was then performed. Load to failure, stiffness, and yield load were compared between constructs using 1-way analysis of variance. Results: The hybrid fixation constructs (IFS/BB and IFS/SB groups) showed significantly better biomechanical properties than the isolated extracortical fixation constructs (BB and SB groups) ( P < .05 for all). There were no differences between the isolated extracortical fixation constructs or between the hybrid fixation constructs in elongation or load to failure; however, stiffness of the IFS/BB group was significantly higher than that of the IFS/SB group (175.3 ± 16.6 vs 144.9 ± 20.1 N/mm, respectively; P < .05). Stiffness between the SB and BB groups was not significantly different. Conclusion: Hybrid fixation had superior biomechanical performance compared with isolated extracortical fixation. However, tibial graft fixation using a bone bridge either as isolated extracortical fixation or combined with an interference screw for hybrid fixation showed equivalent biomechanical properties compared with suspension button–based graft fixation. Clinical Relevance: The clinical use of a bone bridge for tibial graft fixation could reduce the cost for ACL reconstruction and lower the rate of implant-associated issues.

Background Repair of a torn rotator cuff should have sufficient initial strength of the fixation to permit appropriate rehabilitation. Hypothesis Augmentation with a woven polylactic acid scaffold strengthens repairs of the rotator cuff. Study Design Controlled laboratory study. Methods In the suture-anchor model, 10 pairs of sheep infraspinatus tendons were detached and repaired to suture anchors. In half of the matched specimens, the repair was reinforced with a woven poly-lactic acid scaffold repaired with the tendon to bone. In the bone-bridge model, sutures were passed through a trough and over a bone bridge distal to the greater tuberosity; half were reinforced by the scaffold. The repairs were tested to failure with a hydraulic testing machine. Results The mean ultimate strength of suture-anchor repairs augmented with the scaffold (167.3 ± 53.9 N) was significantly greater than that of nonaugmented fixation (133.2 ± 38.2 N). Failure occurred when the tendon pulled through the sutures; the scaffold remained intact. Scaffold reinforcement of the bone bridge significantly increased the ultimate strength from 374.6 ± 117.6 N to 480.9 ± 89.2 N, and the scaffold remained intact in 8 of 10 specimens. Conclusions The scaffold significantly increased the initial strength of rotator cuff repair by approximately 25%.

Abstract:

Recently, the elderly population and excessive use of multimedia devices are increasing, which contribute to the growing number of patients with hearing loss. Hearing aids are used as a hearing rehabilitation method for patients with hearing loss and can be classified as air conduction and bone conduction according to the sound transmission pathway. Bone conduction is advantageous over sound transmission as it does not affect the eardrum. Bone conduction systems are divided into BAHA, Bone Bridge and B81 according to the vibration transmission method. BAHA has disadvantages as it can result in skin diseases and has inconveniences, and patients are reluctant to accept Bone Bridge because it has to be implanted into the temporal bone. Due to its location on the skin, B81 can solve these problems; however, this method may reduce transmission efficiency. In this paper, we have proposed a resonance frequency analysis model of a curved beam diaphragm to solve these problems. The proposed method involved a natural frequency equation with derived parameters. An improved efficiency (vibration transmission) was confirmed using the fabricated diaphragm. In the future, the proposed method may be used in various fields.

Abstract:

The revolutionizing efficacy of recombinant human bone morphogenetic protein (rhBMP-2) for clinical spinal fusion is hindered by safety issues associated with the high dose required. However, it continues to be widely used, for example, in InFUSE Bone Graft (Medtronic). Here, we developed a translational protein engineering–based approach to reduce the dose and thereby improve the safety of rhBMP-2 delivered in a collagen sponge, as in InFUSE Bone Graft. We engineered a bridge protein with high affinity for rhBMP-2 and collagen that can be simply added to the product’s formulation, demonstrating improved efficacy at low dose of rhBMP-2 in two mouse models of bone regeneration, including a newly developed spinal fusion model. Moreover, the bridge protein can control the retention of rhBMP-2 from endogenous collagenous extracellular matrix of tissue. Our approach may be generalizable to other growth factors and collagen-based materials, for use in many other applications in regenerative medicine.

Abstract:

This study aims to evaluate the effect of autologous adipose-derived mesenchymal stem cells (AAD-MSC), with and without synthetic absorbable hydroxyapatite (HAP-91), on the bone regeneration in rabbits. Thirty-four female white New Zealand rabbits were submitted to a 10 mm distal diaphyseal radius ostectomy, divided into 3 experimental groups according to the treatment established. The bone gap was filled with 0.15 ml of a 0.9% saline solution containing two million AAD-MSC (G1), or AAD-MSC associated with HAP-91 (G2). The control group (CG) received only 0.15 ml of the 0.9% saline solution. Radiographs were made post-operatively, and after 15, 30, 45 and 90 days. Fifty percent of the samples were submitted to a histological examination at 45 days and the remaining ones at 90 days post-operatively. Radiographically, the periosteal reaction, bone callus volume and bone bridge quality were superior in G2 (P < 0.05). Histologically, the bone repair was faster and more efficient in G1 at 45 days (P < 0.05). In conclusion, AAD-MSC improved the regeneration on the experimentally induced bone defects in rabbits; however, the use of hydroxyapatite requires caution given the granulomatous reaction produced in the species.

Abstract:

A 74-year-old man developed bilateral lower limb spastic paresis. He was diagnosed with thoracic spondylotic myelopathy presumably caused by mechanical stress that was generated in the intervertebral space (T1-T2) between a vertebral bone bridge (C5-T1) due to diffuse idiopathic skeletal hyperostosis after anterior fixation of the lower cervical spine and a vertebral bone bridge (T2-T7) due to diffuse idiopathic skeletal hyperostosis in the upper thoracic spine. Treatment included posterior decompression (T1-T2 laminectomy) and percutaneous pedicle screw fixation at the C7-T4 level. Six months after surgery, the patient could walk with a cane, and the vertebral bodies T1-T2 were bridged without bone grafting. For thoracic spondylotic myelopathy associated with diffuse idiopathic skeletal hyperostosis, decompression and percutaneous pedicle screw fixation are effective therapies.
